Hi.
Today I finished my first DIY amp for my new Grado's SR80.

I used Ben's schematics (http://www.feistworks.com/ben/a47/default.asp). BTW he is a nice person

I did not used any potentiometers. just skipped it.
the output of the amp is too noisy and no good basses. i also hear a hiss when nothing played. but the hiss disappears when i pull off the input plug from the amp.

any ideas how to fix it? its my first amp. i never heard any good audio equipment. so please help me
